My First Robot "minion"

That is true. I think though, if sfoy has sufficiant torque already and even has to limit the PWM to 50%, then adding a little weight might be more practical without having to change a lot about the robot itself, that would really be a shame because it's sweet looking just as it is.

I think that most of the weight is from the material it is made of, it would be hard to shift the weight without starting over and changing it's entire construction. The camera is also adding weight and probably is the major part that is shifting the weight to the top. Though the cam isn't al that heavy I'm guessing and can easily be compensated for, the rest is mostly the Minion itself.

Just a bit more weight on the bottom might just make that difference between falling over and maintaining stability. You could simply place something in there just to see how far of an effect it really has. Then you could think about what kind of object of similar weight and various shapes could be added.

All the weight is at the bottom. It's not very heavy at all. It's really that it's on a 5" base that's maybe an inch from the ground. If he's on a flat surface he's great. But the base is really small and he's about 17" tall.

He cant move off my carpet in my room (where pc is located) because of the bluetooth.

Yes actually my next project is in the works. I am hacking a robosapien, for his torso. I am using the head from ottobot. I may be using a hearoid omni bit for lower body. Got mini itx. So he will not need a computer. He will have ai.
